摘　　要：采用氯盐、硫酸盐溶液浸泡并进行干湿循环的试验方法,分析讨论了水胶比、沸石掺量对混凝土抗氯盐及抗硫酸盐侵蚀性能影响的规律。试验结果表明:水胶比的降低可延缓腐蚀,掺入沸石粉能提高混凝土的抗硫酸盐侵蚀性能,但沸石粉的掺入量不是越多越好,存在一个限定值,当超过限定值时,会破坏混凝土内部结构,导致其抗氯盐及硫酸盐性能下降。By using drying and wetting cycles in chloride and sulfate solution, the effects of several factors on the resistance to chloride and sulfate attack of concrete were studied, the factors include： water binder ratio, content of Zeolite. The results show that the decrease of water-binder ratio, increase of addition of air-en-trained agent and addition of Zeolite improve the resistance to ion attack of concrete in different extent （sulphate or chloride acid solution）. The content of zeolite powder has limits, when the content exceeds the limit, and the concrete will destroy the internal structure, leading to its resistance to chloride and sulfate salts performance degradation.
